Investigations of grinding burn on a nitrided steel

Abstract

Grinding process may lead to the occurrence of grinding burn. When the temperature in the contact zone gets too high, it may lead to damage of the workpiece. The target of this study was to characterize changes occurring in the material after grinding burn on a nitrided steel. The microstructural changes after burn were quantified, by using residual stresses, Raman spectroscopy was also use to detect and characterize different oxides, appearing after grinding burn. The study highlights the possibilities of using this last non destructive method for detecting and quantifying grinding burn.
